my husband has been home for just over a year. we're reconnecting but it's still unclear as to what end. we behave as a family, eat together, go out, share a bed most of the time (he works rotating shifts), but still follow the terms of our separation (he pays me support...) so a bit strange, i guess.
ANYWAY, he had asked, a full year prior to him moving back, to come home and I sort of deflected, redirected, so on, it had been a long journey for me, to say the least and I really didn't want to disrupt the life i now (then) had....but in one of the discussions, he had said to me something i had heard here on this forum years before: "they will leave the OP when the pain of staying with them outweighs the pain of leaving". The way he said it was more along the lines of "she's become much more trouble than she's worth and here is where I'd rather be". He eventually stopped asking so i had assumed they made up but within the year, he had moved in all his totes (which had been packed for months at that point, he told me). He had been living with her for almost 8 years at that point and likely seeing her for 9 years.
It's never a clean break, unless one of them dies. Just within the last month, after months of no contact, she's been back in contact with him in dramatic fashion (first accusing him of harassment, causing him problems with work, then immediately declaring her undying love for him and wanting him back so they can have a child together), but he shut her down. her last contact, a few weeks after that, was through his friend to let him know that she is now pregnant with her current boyfriend's baby (they bought a house together six months ago). husband couldn't get home fast enough to tell me the news.
